Hello Jesse 33,
I am sure that you have done your very best in the test that you took and it sounds as if you are doing well in school. It’s always very tricky to tell exactly how you have done when you have taken a test.
Your Mum supported you and provided extra tuition because she wanted you to have the opportunity to be better prepared. Failure is not having a go at all, rather than giving yourself a chance – as you have.
Worrying will not change anything now. If you don’t pass it really is not a disaster. You will have gained plenty of new skills and greater confidence from the tuition and exam preparation. These will help you in whatever school you move on to for your secondary education.
